Watching the movie, it looks like it pulses on and off. Not a hard blink on/off though, more like a dimming or fading. Like maybe 1.5-2 seconds gradually brightening on, then 1.5-2 seconds fading off. (the actual intervals need to be verified)

Hmm. I think I know just enough about electronics to rig up an "on-off" blinking circuit, but I don't know if I could do the gradual "fade-blink" that you're describing. Hyperdine...oh Hyperdine...we may have a job for you!

I agree with MP...I just watched the movie again this morning, ans it does like a permanent-on light with a blinking/dimming on-off effect on it, which makes it more brighter when it does that. Just an opinion.

ok i go to the hardware and see this(check the pic), and then i search on the website and here is,

the only problem with this is the size, its to damn big, just the "beacon" part its like 5 or 6 cms or more, and i foun this pvc too

but im still looking one with the correct size or closer

Well, I tried to light up my hollowed out, resin beacon last night. I bought, from Radio Shack, a 9volt prong (with the - and + wires, a toggle switch, some extra wire, and a light I had which had a small socket and two lead wires already soldered to the base. I attached the battery leads to the toggle, and two wires to the toggle to the light. I have a circuit board from an emergency light that has a flasher, I plan on adding that to the middle to create the beacon flashing. I tried it and it seems to work) The toggle worked fine. I had it on the dining room table in the off position and BANG! The battery exploded!!!!!!!!!!!

What did I do wrong? I am just glad this was not sealed up in my JP!!!

I would really appreciate any help from you electroning gurus.

I would have loved to buy one of those cool beacons that were offered here, but I was unemployed for a year and can't really afford anything like that right now.

I have only heard that the reason for a battery to explode is because of very high temperatures. Was it an old battery??
I am glad you did not had it in your hand when it exploded, it could of been a worst dissaster.

I'm no expert, but it sounds to me as if the switch was the problem. I know you can buy them as a open loop & closed loop configuration. It sounds like when you had the switch in the off position the circuit back to the battery was complete. Did you notice the battery getting hot at all?

sounds like a problem I had with my last fan setup. I had a simple on/off switch, battery and fan set up. The battery connection had a red a black wire and I attached one each to the switch, then connected the fan the same way one wire to each post. I noticed the fan didnt go off and the battery got very hot. then I realized what I needed to do is simple connect the wires in a way that would have the switch attached to only one color. So that way my two black wires are attached to each other and one red wire is attached to each post on the switch. So maybe you were like me and just need to fix your wiring, simple mistake.

Yeah, that's connecting everything all together (i.e. pos and neg permanently looped together), which you don't want to do. A switch should only go on one set of wires, not both. Sounds like this is what may have happened.

Believe me, I would have loved to get BKBT's self contained beacon, but funds are tight and I already had the resin beacon cut out.If this works the way I am hoping, I will have a steady white strobe (not fast flashing).

Hey guys, I've read some threads and found some info that the beacon could be a Braun Curling Iron tip, and here's the amazing info I found!! I know it's not the same, but it sure does look like almost dead on! All it's missing is the groove around the middle.
